    Default 4.3 to 6.0 swap NEEP HELP PLEASE!!!

    Im doing a 4.3 with manual trans to a 6.0 engine out of an escalade that was automatic, what can i do about the wire harness to be able to connect it to my manual trans???? Another question everythings hooked up to the engin other than the trans wires on the wire harness, the engine starts and then shuts off after about 2-3 seconds. Could this problem be vats??? Im using the stock pcm that came with that engine???

    VATS is the most likely culprit.

    I got the vats removed and my truck started right up, 4 days later i go to start it and it doesnt want to start???? I replaced the battery also and it still seems like the truck struggles to crank, like if the battery was low but its brand new
